COMBINED HEAD AND SIGNAL LAMP.

Specification of Letters Patent.

Application filed July 10, 1916. Serial No. 108,371.

To all whom it may concern:

Be it known that I, ELMER J. Boos, a citizen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Combined Head and Signal Lamps, of which the following is a specification.

This invention relates to a combined head and signal lamp and has for an object to produce a combined head and signal lamp which will give distinguishable slgnals for indicating to approaching cars, trains or other vehicles when a vehicle equipped therewith has been stopped, thereby avoiding collisions. A further object is to produce a combined head and signal lamp for use on traction cars and trains, which will indicate on what track a car or train is located. A further object is to produce a combined head and signal lamp, which will give warning of the approach, of a vehicle equipped therewith.

These and other objects are attained in the construction described in the following specification and illustrated in the accompanying drawings, in which,

Figure l is a front elevation of a combined head and signal lamp embodying my invention.

Fig. 2 is a vertical sectional view of my improved head and signal lamp.

The combined head and signal lamp embodying my invention consists of a casing 3, in the front of which is mounted a head lamp 4 and in the top of which is mounted a series of signal lamps 5, 6 and 7, the signal lamps being arranged in fan-like relation to one another. A series of three signal lamps is provided, the centrally located lamp being mounted to direct a shaft of light vertically and the remaining two signal lamps being mounted to direct shafts of light at opposite angles to the vertical shaft, each of the an les being preferably degrees and all of t e signal lamps being located so as to throw their rays in a vertical plane extending transversely of the car or train. Each of the lamps 4, 5, 6 and 7 consists of a reflector 8, preferabl of parabolic formation, having any suita le source of illumination 9 located at the focus thereof, and closed by doors 10 consisting of annular frames 11 and glasses 12, these doors being mounted in any suitable manner, as for example, by means of hinges 13 located on one side, and catches 14 located on the opposite slde, the catches and hinges being arranged to avoid interference of one door wlth an adjacent door when the doors are opened. I have preferably located the hinges of the doors of signal lamps 5 and 7 so that the doors may be opened, to the dotted lined positions shown in Fig. 1, the hinge of the door of signal lamp 6 being located so that it may be thrown to the rear and opened to the position also shown in dotted lines in Fig. 1. The door of the head lamp is provided with a hinge located at one side, this hinge permittin of the door belng opened to the dotted llned position shown in Fig. 1. Thus access to the interior of the lamps may be had for the purpose of repairing and cleaning them. I have shown the combined head and signal lamp embodying my invention, as being designed to be illuminated by means of electricity, any suitable source of power 15 being provided, with switches located in the circuit therewith. A switch 16 is provided to control the illumination of head lamp 4., with switches 17, 18 and 19 provided for controlling the illumination of the respective signal lamps 5, 6 and 7.

In using my combined head and signal lamp, the head light 4 and signal light 6 is intended to be left burning throughout the hours of darkness requiring its use. If the vehicle is proceeding in one direction, one of the lamps, as for example signal lamp 5, will be illuminated. The shaft of light from this source will be projected at an angle into the air and will be .visible to a vehicle approaching the first mentioned vehicle. If the approaching vehicle is likewise equipped, one of its lamps will be illuminated so as to project a shaft of light in the opposite direction, this being a warning to the first mentioned vehicle. Should the motion of the vehicle be reversed, so that it travels in an opposite direction without turning around, as for example when backing up, the opposite signal lamp 7 will be illumlnated, thus projecting a ray in the opposite direction. The lamp 5 or 7 which project their shafts at angles intothe air,

are intended for illumination when the vehicle is stopped. These angle shafts will then act as a warning to following as well as to approaching vehicles and thus avoid collisions with the standing vehicle.

Having thus described my invention, what I claim is:

1. A combined head and signal lamp comprising a casing, a series of lamps mounted in the casing, one of said lamps facing front to cast a shaft of light in a substantially horizontal forward direction in-front of the vehicle equipped therewith, and each of the remaining lamps being located in a vertical plane extending transversely of the vehicle, one of said lamps being adapted to cast a shaft of light vertically and the remaining lamps being adapted to cast shafts of light at angles thereto and in the vertical plane.

2. In a combined head and signal lamp the combination of a casing,a series of lamps mounted in the casing, and means for controlling the illumination nf the lam s, one of said lamps facing front to cast a s aft of light in a substantlally horizontal forward direction in front of the vehicle equipped therewith, and each of the remaining lamps being located in a vertical plane extending transversely of the vehicle, one of said lamps being adapted to cast a shaft of light upwardly and the remaining lamps being adapted to cast shafts of light at angles to the second shaft, to each side thereof, and in the transversely extending vertical plane.

In testimony whereof, I have hereunto subscribed my name this 6th day of July, 1916.
